IMPROVEMENT IN RESERVOIR COOKlNG-STOVES.'

Specification forming part of Letters Patent No. 133,081, dated November19, 1872.

To all whom it may concern:

Be it known that we, MARK CURTIS and LEWIS E. GLOW, both of St. Louis,county of St. Louis and State of Missouri, have made a certain new anduseful Improved Cooking- Stove; and we do hereby declare that thefollowing is a full and true description thereof, reference beinghad tothe accompanying drawing and to the letters of reference marked thereon.

The nature of the improvements here presented relate, first, to thepeculiar construction of the front part of the stove to form anauxiliary flue, whereby a direct draft from tireplace under the boileror hot-water reservoir is achieved; secondly, to the arrangement andcombination of a hot-air passage from ash-pit with a cold-air flue, tocreate a more equal and continuous heat and burning of the fuel-matter,said cold-air flue further being provided with draft-holesto equalizethe temperature of heat in the oven, and to carry off its superfluousheat and gases to assist process of combustion thirdly, to thearrangement of a hearth on either side of stove with or withoutsoot-chamber and soot-pan, whereby the lower flue of the oven can becleansed without inconvenience and uncleanliness; fourthly, in providingand forming the hearth to have a furnace or grate in front of ash-pit,adapted for purposes of the ordinary charcoal furnace; fifthly, tocertain detail construction and appurtenances, all of which will nowmore fully appear.

To enable those herein skilled to make and use our said improvements, wewill now more fully describe the same, referring to Figurel asalongitudinal sectional elevation to Fig. 2 as a part topplan, showingparts seen with cover partly removed to Fig.3 as a part longitudinalsection at line as w; and to Fig. 4 as a transverse section at line asw.

The general outline of the stove is as shown in Fig. l.

The stove or range A has the fire-box B, ash-pit O, oven D, and acontinuous flue, E, surrounding the oven. (See Fig. 1.) F is the boileror hot-water reservoir, positioned in front of the stove, in closeproximity to the fireplace B. In order that the direct benefits of theheat from the fire-chamber B shall be utilized and made to surround thebottom of the reservoir F, the front face or casing G of the stove forthis purpose is made to form an auxiliary flue, E, as indicated inFig. 1. Further, the flue-partition e is curved inward at top, so as topartly correspond with flue E. A continuous flue is thus made by thecommunication of the flue E and extension-flue'E, creatin g a directdraft under the hot-water reservoir. To regulate the passage of heatthrough the flues E E as desired, the opening 6 is provided with aproper damper, e". The heat or hot gases can thus be made to passaroundthe oven D through flue E, imparting an equalizing heating effect to theoven; or the heat can be directed into the auxiliary flue E, to betterand quickly heat the reservoir. Between the fire-place B and top part ofthe partition e the hot-water back or chamber H is situated. Saidchamber is constructed to form part of the fire-place B, and yet isdivided from the partition 0, thus enabling the full and di rect actionof heat from fire-place to surround the bottom and reach the oppositesides of said chamber. The hot-water chamber H is provided with properpipeson' opposite sides,

obviating the necessity of passing said pipes over the top of the oven,as usual in stoves or ranges. The fire-chamber B has its opposite backsb b corrugated, as ordinary. B is the ordinary revolving grate in thefire-chamber. Back of the fire-place B and forming part of same is ahot-air chamber or passage I. Said passage is arranged to communicate atbottom with ash-pit, and at top is provided with a series ofperforations, i, as clearly shown in Figs. 1 and 2. Further, immediatelyjoining the back, at top of the hot-air passage I, is the coldair flueI. Said flue I is made by joining the top and front oven-plates, (seeFig. 1,) in constructive nature forming a transverse tube,

admitting cold air from both sides of the stove. A. hole, i is providedin the cold-air flue, sufficient to allow a cold-air draft to enter ovenD to equalize the temperature of heat in-same; a further hole, i beingmade in hot-air passage I to allow all superfluous steam, gases, andheat from oven to escape into said hot-air passage and pass out of same.Further, it will be noticed that the hot air, carbonaceous matter, andgases from fire-place, ash-pit, during exit out of hot-air passage I,commingle and otherwise combine with draft from coldoffset K at bottomof stove. offset K is combined, so as to form part of vantages ofestablishing a more uniform distribution of the heat throughout thestove. By this arrangement, also, the hottest part of the oven is keptmore cool, the heat is tempered on the oven-plates, all dampness intheoven is dried, and the process of cooking and bakin g is renderedmore wholesome. Arranged on either side of the stove is a hearth-plate,J, for general convenience of supporting articles. To clean the flue Efrom soot and other impurities, the same are raked to the front into theFurther, to the same, a soot-chamber, 70. Said soot-chamber projectsnear to the outer line of the hearthplate, and is provided with asuitable sootpan, Id. The opened end of the ofi'set K has a slide-door,k Thus all the sooty matter raked and collected in said offset can begathered and deposited in the soot-pan k and carried away, and theinconveniences ordinarily resulting in cleansing the oven-flue is thuspractically avoided. Forming part of the hearth-plate J is a grate orfurnace, 7', made by closing the sides between hearth and sootchamber k,as indicated in Fig. 3. j is a suitable grating placed in furnace. Thedoor j of the ash-pit is grated (see Fig. 4) to allow the smoke andconsumed products from furnace to escape in the ash-pit. The soot-pan kserves as a draft-regulator for the furnace. 7' is alid to close hearthand cover furnace when the latter is not used. A suitable furnace isthus combined with the stove, answering all purposes of the ordinaryhousehold charcoalfurnace. A proper cap or blower, j, can be formed tobe placed over the furnace to create further draft, and to carry ofl'fumes, gases, and the like into ash-pit.

Having thus fully described our said invention, what we claim, is

1. The flue or chamber E, communicating beneath with flue E, and atitsupper side with fire-box B by an opening, 6 into which I thewater-reservoir so sits that the entire pit thereof may be exposed tothe heated products of combustion, substantially as described.

2. A hot-air passage, I, when arranged back of fire-place andcommunicating from ash-pit, and combined with cold-air flue I and draftholes 1' i i i substantially as and for the purpose set forth.

y 3. A hearth-plate arranged on either side of stove, provided withsoot-chamber 7c and pan R in combination with the offset K of stove A,substantially as and for the purpose set forth.

4. The hearth-plate J, grating or furnace j, soot-chamber k, pan 70,when arranged in combination with ofiset K and stove A, as and for thepurpose set forth.

In testimony of said invention we have hereunto set our hands.
